Kaiser Aluminum Corporation is a Delaware-based manufacturer of semi-fabricated specialty aluminum products, including plate, sheet, coil, extrusions, drawn tube and rod, and certain cast products. It focuses on demanding end markets such as aerospace and high-strength applications, beverage and food packaging, general engineering, and automotive extrusions, targeting high barriers to entry and premium pricing.

The company serves primarily North American customers, with many blue‑chip manufacturers and tier one suppliers, and its largest customer represented 16% of net sales for both 2024 and 2025. Kaiser emphasizes capital investment at its Warrick and Trentwood facilities to expand capacity, reduce conversion costs, and enhance KaiserSelect® product performance. As of June 30, 2025, non‑affiliate market value of its common stock was about $1.3 billion, and 16,210,443 shares were outstanding as of February 16, 2026. Key risks include cyclical demand in aerospace and automotive, competition from large global aluminum producers and alternative materials, exposure to metal and alloy price volatility despite hedging programs, and potential disruptions from labor relations, macroeconomic conditions, and geopolitical factors.

Kaiser Aluminum Corporation reported stronger fourth quarter and full year 2025 results. Fourth quarter net sales were $929 million, up about 21% year-over-year, with net income of $28 million, or $1.68 per diluted share, and adjusted EBITDA of $88 million, a 24.1% margin on $365 million of conversion revenue.

For full year 2025, net sales rose to $3.37 billion from $3.02 billion, and net income increased to $113 million, or $6.77 per diluted share. Adjusted net income was $100 million and adjusted EBITDA reached a record $310 million with a 21.3% margin. The company improved its net debt leverage ratio to 3.4x from 4.3x and generated enough cash to fund working capital, capital investments, interest, and $51 million of dividends, including a quarterly dividend of $0.77 per share.

Management expects 2026 conversion revenue to grow 5% to 10% and adjusted EBITDA to rise 5% to 15% year-over-year, citing strengthening operations and recent investments, while acknowledging shipment softness from aerospace destocking and slower packaging ramp-up in 2025.
